First of all, you assume that it is possible to make "one big core equal in processing power to the 8 cores". I don't think it is possible to do this (at least not with the x86 architecture using today's technology.)
But assuming such a chip exists, the answer depends on what kind of efficiency you're thinking of.
If you mean computational efficiency (meaning the most useful processing per clock-tick), then a single big core will do better. This is because single-threaded apps will be able to use the full power (whereas multiple threads are needed to take advantagte of multiple cores.) Also, the operating system can get rid of the overhead that is needed to keep software running on the multiple cores from stepping on each other.
If you mean energy efficiency (amount of processing per watt of electricity consumed), then it could go either way, depending on how the chips are made. But given today's manufacturing processes and the non-linear power curve that we see as clock speeds are increased, the multiple-core solution will almost definitely use less power.
I remember hearing about how it is possible to make multiple cores act like one (Idon't remember where I heard this). Anyways, whether 8 cores acting separately or together like 1 big processor has an advantage depends on the program you use. If the program is multi-threaded, then the cores acting separately might have the advantage while single threaded apps will have an advantage if the cores are acting like one. However, many apps today won't see that much improvement either way (like a simple calculator, or solitare and word processing).

So another patch for today adding mechanical damage. Must have the newest firmware...
only online so far. It was a good fix, cuts down on the bumper cars in certain rooms...

I have just ordered a mbp :( It wasn't supposed to ship until Monday but it shipped early :( If the rumors are true will I be able to send it back and get the new one? Has anyone had any experience in returning unwanted stuff to apple as time is not on my side (leave for uni on the 16th Sept)
I never have but I hear it is pretty easy if you DON'T OPEN THE BOX.
The only change is likely to be the cpu. The rest of the MBP will probably be kept the same and if you look at the yonah vs merom benchmarks at places like AnandTech, it probably isn't worth sending it back.
It has been rumored that there might some minor changes to the computer such as easilly removable HD, differnt latch, as said above. But more importantly, I hope they bump the clock speeds and include 1GB RAM as standard on lowest MBP model for the same price.

Best Buy isn't the only place to buy these... I've thought through the various marketing gimmicks, and really none apply here. Why would they do this...
May be they did not want to embarrass the Xoom too much :rolleyes:

Whats the point? Its history.
My guess is, that its how Tiger is now.
Because it is a 64 bit proccessor that's the point.

I wonder if altering the typical refresh cycle is due to the Verizon release early this year. I think Apple can afford to play the hardware waiting game if two things:
The new hardware is a big step forward. Part of this is producing one iPhone, regardless of carrier (AT&T and Verizon) as well as compatibility for international travelers. More storage and a much improved processor are givens. I�m really surprised how �laggy� the iPhone 4 feels. A bigger display (without altering the phone�s dimensions) would be icing on the cake. Other than that, hasn�t what can be crammed into the hardware plateaued?
iOS 5 should also a big step forward, and it should come this summer in order to appease those waiting for iPhone 5. iOS really needs to liberate itself from requiring a PC to sync with. This is especially true in regards to the iPad, which is/will become the sole �computer� for a large demographic. But for this to happen, I�m pretty sure iOS will need some sort of file system as well as the ability to mount and be mounted as external volumes. The UI also needs a revamp with some sort of new �secret sauce�.

Hey, I'm not about to complain, they sent me a brand new MacBook Pro (even though I was on hold for an hour). Yeah, I have certainly noticed longer hold times on the support lines. Crazy, huh?

I have a few quick questions for anybody that works at Radio Shack:
I plan on going into a Radio Shack store on Tuesday to look into Appraising my iPhone. Do I need the Original Box? I have the Accessories and the books that came with my iPhone, but don't have the box.
nope, just the phone :)
Also can I just get an Appraisal without having to agree to it? and
Does my phone have to be resorted to factory setting and my info wiped off if I'm just going in for an Appraisal?
yes, we log in and appraise it, then you can either agree or decline. just tell them you are wanting to know for the launch. It's after you say "ok sounds good" that we start the actual point of sale process. The phone doesnt have to be wiped, just no passcode.
If I decide to go along with the Appraisal and Pre Order an iPhone 4 does the store take my iPhone that day? Or do I keep it until I get the iPhone 4?
You will want to do the trade in when you pick the phone up. We havent got official word on the preorder process for the iphone 4 but if its like the evo, it will work like this...
You pay $50 and we give you a gift card for that ammout and a reservation. When you come in to pick up your (example) $199 phone we apply the $50 ngift card making it 149 you pay right then, then we do the trade in and take that ammount off the 149. :)
I was also wondering if it makes any difference in the appraisal if the phone is a Refurbished or not? My Girlfriends is a Refurbished one.
Refurbs trade in jsut the same as a new one. think about it like this... A refurb is a used phone, and you are trading in a used phone anyway. :)
Sorry for all the questions.
Thanks!!!
no worries bro, hope i could help! :)

I'm not from the US so if someone with some legal background over there could point out to me how this would work..? Where I'm from you have to have suffered damages in order to sue someone, otherwise a government regulator would just impose a fine on the company or require them to stop what they are doing..? How have these people (who are suing apple) suffered losses as a result of this apparent spying technology..?

If the power consumption is the same... does that mean that the Merom and the current chips suck the same amount energy while going full throttle?
If the above is true, if you turned down the Merom to match the speed of the current chips, wouldn't the Merom be drawing 20% less power?
In other words if the Merom and the current chip were both going 60 mph down the freeway, would the Merom be drawing less power?
Am I missing something here (such as the basics of electricity, the basic way that chips work, etc.)?

Well, if you're located and in SF and are you are a Safari user, or have questions about Safari, or maybe even questions about what SJ shows Safari-wise or other webkit-related content in Leopard, you don't have to shell out for WWDC admission, because the Safari/webkit folks are hosting a freebie (http://webkit.opendarwin.org/blog/?p=63) on Tuesday at 7 that's open to all.
If you are a Mac OS X developer, a browser hacker, a web developer, or just someone with an interest in cool technology, then come hobnob with WebKit contributors from Apple and elsewhere. Unlike WWDC itself, this event will be open to anyone who is interested free of charge. Also, it will be unbelievably awesome. We promise!

Christ I am so sick of them taking fantastic hardware and absolutely ruining it by using proprietary file formats and frankenstein versions of Android. I do get a kick out of their 10.1" model being both thinner and lighter than the 9.7" Ipad2 though. That will undoubtedly have the apple apologists out en masse.
Yes 2 tenths of a millimeter thinner and 6 - 12 grams of weight difference... I'm sure the "apple apologists" are losing a lot of sleep over that one :rolleyes:

Use the dashboard clock widget if you're in the UK and open a clock then set it to Cupertino..
Correct, the time difference is plus 8 hours. Good call on the widget usage. :p

I'm glad that Leopard will be completely (that's what they say, at least) 64-bit. I'm not sure why it's important to go on about the applications as if they were important to the operating system itself. Increased integration like what was displayed would cause the anti-trust machine to whip into action, if it was Microsoft instead of Apple.
Time Machine is not exactly revolutionary, considering that there were a few 3rd party products available--Rewind comes to mind--that journaled changes and allowed them to be restored. Still, it should stop the various threads "I accidentally deleted..." :)
Hopefully, the features not mentioned will include a better kernel that actually performs well. It would be nice to see operating system benchmarks that don't make me cringe when I look at the Mac OS X results.
Xcode version 3.0 looks good but they still haven't provided many details.
Yeah, my first thought was - oh yeah, that's just like Rewind. However, the poweronsoftware.com website now forwards to http://www.nowsoftware.com/, so maybe Rewind has been bought out by Apple to use as Time Machine. Anyone know any more about this?

The tone has not been warm to this point. Read the first few pages of the posts. There was a lot of Apple-blasting on pretty silly grounds. It's not like it's months and months later (a pattern we used to have with Apple all the time). It's a matter of a couple weeks -- MAX. Like I said, you and others can wait if you want. Heck, I have a MB and a MBP and am probably going to sell the MBP soon and wait for a revision myself. But the implication that many posts had, such as that the world was coming to an end, was pretty darn ridiculous.

Can't believe it's anywhere near GM time. Way too many bugs and inconsistencies in behavior. New networking tools in Server have to be implemented now that SMB is being canned - that's not a minor addition. Calling it a release candidate is a stretch, but calling it GM is just plain crazy.
